Abstract

Abstract Flexible perovskite solar cells (f‐PSCs) have emerged as potential candidates for specific mechanical applications owing to their high foldability, efficiency, and portability. However, the power conversion efficiency (PCE) of f‐PSC remains limited by the inferior contact between perovskite and flexible buried substrate. Here, an asymmetric π‐extended self‐assembled monolayer (SAM) (4‐(9H‐dibenzo[a,c]carbazol‐9‐yl)butyl)phosphonic acid (A‐4PADCB) is reported as a buried substrate for efficient inverted f‐PSCs. Employing this design strategy, A‐4PADCB exhibits a significant orientation angle away from the surface normal, homogenizing the distribution of contact potentials. This enhancement improves the…
